DNC chairwoman won't repudiate Reid's tax claims

8/5/12 11:08 AM EDT

The head of the Democratic National Committee on Sunday refused to repudiate Harry Reid’s allegation that Mitt Romney hasn’t paid a decade’s worth of income taxes.

“Everybody is responsible for saying the things that they have information on. Harry Reid says that he has a credible source,” Rep. Debbie Wasserman Schultz (D-Fla.) said on ABC’s “This Week.”

“I know that this question is not just generated by Harry Reid. It's been asked by countless reporters, by voters that want to know more about Mitt Romney's finances. What is he hiding?

“I stand by the fact — George, I stand by the fact that I believe, like the overwhelming majority of voters believe, because the polls all show, that Mitt Romney owes us more than one year of tax returns.”

Romney has said there’s no truth to the Senate majority leader’s unsubstantiated claims and called on Reid to “put up or shut up.” He’s released the past two years of his returns but has refused to release any more.

Wassermann Schultz said Romney could clear up questions in “10 seconds” by releasing his returns.

“I do know that he could clear it up just like that, lickety-split, by releasing his tax returns, which every major candidate for president of the United States has done except for Mitt Romney,” she said.
